From source file:Main.java

public static void main(String[] args) throws Exception {
    DatagramSocket ds = new DatagramSocket(3000);
    byte[] buf = new byte[1024];
    DatagramPacket dp = new DatagramPacket(buf, 1024);
    ds.receive(dp);//from  ww w .  j  ava 2 s  .c o m
    String strRecv = new String(dp.getData(), 0, dp.getLength()) + " from " + dp.getAddress().getHostAddress()
            + ":" + dp.getPort();
    System.out.println(strRecv);
